Description

Technical Field

[0001] This utility model relates to the field of plaster patch technology, and in particular to a double-compartment acupoint patch. Background Technology

[0002] Plasters are a commonly used form of topical medication. They typically involve mixing the medication with a suitable base to form a paste, applying it to a material that comes into contact with the skin, and then attaching the entire material to the skin. Common plasters usually consist of three parts. The outermost layer is the backing layer, generally made of non-woven fabric, polyethylene, or similar materials. It is soft, has a certain strength and toughness, and serves to hold the medication. The middle layer is the medicated plaster layer, the core of the plaster, made by mixing the medication with a suitable base. Its color and texture vary depending on the medication and base; for example, traditional black plasters are relatively hard, while the medicated plaster in medicated plasters is often gel-like and lighter in color. The innermost layer is the adhesive layer, used to adhere the plaster to the skin surface. A release liner, usually silicone paper or a plastic film, is placed outside the adhesive layer to protect the plaster before use, preventing contamination or drying. This release liner is removed before application.

[0003] Although medicated plasters can be absorbed through the skin, the absorption rate is relatively slow and the amount absorbed is limited compared to oral or injectable administration. For some patients with severe conditions requiring rapid relief, this may not meet their treatment needs. Increasing the dosage can not only cause significant skin damage, potentially leading to allergic reactions such as itching, redness, and rashes, but also result in an unpleasant odor and high irritation. Furthermore, medicated plasters are usually quite dry, which hinders absorption, requiring longer application time to achieve the desired effect. Prolonged application time can also cause allergic reactions such as itching, redness, and rashes. If the plaster is made into a gel form, it is difficult to store, and the efficacy may decrease or even disappear over time. Currently, some medicated plasters come with a spray, which is applied after the plaster is applied and then mixed with the medication. However, this method is cumbersome, and the spray is uneven and does not promote proper mixing. Utility Model Content

[0004] To address the shortcomings of the existing technology, this invention provides a dual-compartment acupoint patch. By designing a patch with two compartments, dry and wet medications are stored separately and then mixed before use. The wet medication activates the dry medication, promoting drug absorption. Specifically, the technical solution of this invention to achieve the above objective is as follows:

[0005] A double-compartment acupoint patch, comprising:

[0006] The adhesive part is provided with a backing layer, a matrix layer, and an anti-adhesion layer; the backing layer covers the matrix layer, the matrix layer includes a filling area in the center and an adhesive area around the filling area, the filling area is used to fill dry drugs; the anti-adhesion layer covers the matrix layer and covers the filling area and the adhesive area.

[0007] The liquid storage section is used to store liquid; the opening of the liquid storage section extends laterally through the adhesive area and connects to the filling area, and a partition baffle is provided at the connection.

[0008] The liquid storage section includes a heat-sealing bag, the opening of which passes through the adhesive area and is finally connected to the filling area; a partition is installed at the opening of the heat-sealing bag to separate the heat-sealing bag from the filling area; the interior of the heat-sealing bag is used to store liquid.

[0009] The liquid storage section also includes an airbag, which has a sandwich structure, and the heat-sealing bag is installed in the sandwich structure of the airbag and is under the compression of the airbag.

[0010] The top view of the partition plate is S-shaped.

[0011] The backing layer includes a heating layer, a breathable layer, and an anti-oxidation layer; the heating layer is disposed above the matrix layer; a breathable layer is disposed between the heating layer and the matrix layer; the anti-oxidation layer covers the top layer of the acupoint patch; and a breathable layer is disposed between the anti-oxidation layer and the heating layer.

[0012] The filling area is wrapped with a wrapping layer, which is a non-woven fabric or a breathable adhesive tape.

[0013] The top view of the adhesive part is a square with a side length of 2cm; the top view of the filling area is a circle, located at the exact center of the adhesive part, and the diameter of the filling area is less than 2cm.

[0014] Before use, the acupoint patch is stored in a sealed bag. When using, remove the acupoint patch from the sealed bag, then bend the partition 21 to break it off. After breaking, the liquid reservoir 2 is connected to the filling area 11 of the adhesive part 1. The pressure of the air bladder 23 in the liquid reservoir 2 forces the liquid in the heat-sealed bag 22 into the filling area 11 to mix with the dry medicine in the filling area 11. After all the liquid in the liquid reservoir 2 has flowed out, cut off the liquid reservoir 2, peel off the anti-adhesive layer 13, and attach it to the application site through the adhesive area 12. During use, the filling material in the heating layer 14 generates a certain amount of heat after contacting air and moisture.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention features a dual-compartment design to store dry and liquid medications separately, which are then mixed thoroughly before use. This enhances the user experience, extends the shelf life of the medication, and ensures better efficacy during use.

[0017] By combining essential oil liquids with dry medicines, the disadvantages of traditional plasters, such as unpleasant odor and high irritation, are overcome, and the aromatic, antioxidant, antibacterial and anti-allergic properties of the essential oil liquids are brought into play.
